    * PROBLEM DESCRIPTION: ABEND04E RC00C20221 in DSNB5PCO.        *

    ****************************************************************
    If a pageset castout is processing a long list of pages, there
    is a processing loop in which it is not serialized with a GBP
    rebuild except for the first time through.  Therefore there is a
    timing window in which a GBP rebuild can invalidate the connect
    token being used by the castout, resulting in an ABEND04E
    RC00C20221 in DSNB5PCO.
    Additional symptoms: RC00C20223 DSNB5ULK +0C70
    Dump Title: DBW4,ABND=04E-00C20223,U=SYSOPR  ,M=N  ,C=101.BMC
                 -DSNB5PCO,M=DSNTFRCV,LOC=DSNIDM  .DSNB5ULK+0C70
    

Problem conclusion

  • The castout logic has been modified to ensure that the read-for-
    castout process is always serialized with a GBP rebuild.
